The turbo will be going where the washer and coolant bottles are, they get relocated to the battery side, batter goes in the back. I'll be running Megasquirt II

Here are some pics of the engine build:

Block Pep:

Short Block Assembled:
Image

Image

Image

Oversize valves installed
Image

Test fitting of the head
Image

Closeup of the springs
Image

Port work and a tracing of the intakes, The 01+ sits a little high so I'll be modifying it
Image

Intake flow matched, port matched and pin holes elongated
Image

Mopar Roller Rockers installed
Image

Image

Ported the thermostat housing:
Image

The block is a 4.0 but It's going in an Eagle which presents the unique problem of the axle bracket and a block reinforcement rib
Image

So I ported that too
Image

Image

Making a deep sump oil pan:
Image

The Turbo, Garrett T3/T4 60 trim
Image

BOV and Wastegate
Image

This is not even it's final form:
Image

A bunch more stuff for it is in boxes but I'll post all that as it's going in.

Ok, we're on to engines and fun parts, this is my favorite part of a build.

Very nice job, and good call on the megasquirt. I installed an MS-I with the MPI intake on a 258 a few years back, so I will chime in as I can with things I learned along the way. Though much of my lessons are not going to be an issue with the 4.0 setup, as it's already adapted well for the MS conversion with the necessary sensor points. With the MS-II it's going to be nice to fully use the IAC valve, which is something I could not do with MS-I. The extended fuel map is going to be a huge advantage for you as well. I assume you're going to run a wide band O2 sensor? Tuning a fuel map from nothing for a forced induction engine gives me the heebie jeebies.

AND.... is that glyptoil I see in there? Never used the stuff before, but always found it tempting. Would love to hear more of your experience with the stuff. Also very curious about that saddle on the main bearing caps.

Speaking of oil, the custom sump is just cool to see. Going to incorporate a scraper or windage tray in there? With the turbo, have you considered something like the Amsoil bypass oil system? I won't be running a turbo on my build, but I am building for higher RPM's and dirty conditions. So I'm likely going to be using it on my 199.

Thanks! I've been following your build too, can't wait to see how it comes together.

Probably, but I have been working on the body first. Built the engine a while back and then realized there were major structural issues with the car. Once I'm putting the engine in I'll be figuring out sensors and stuff. Also have to contact the guy that built the XJ-R Cherokee. He's running a turbo 4.0 w/ the MS-II setup. Hoping he'll have some good pointers (and maybe a few good fuel curves)

Yes, this was/is my first time using it in an engine. Some old timers swear by it, after putting it on I can see why. It's a rock hard coat that seals everything and it's incredibly smooth when dry. Used foam brushes (which eventually dissolve) and "painted" all unmachined surfaces. It took about 2 coats to cover everything evenly. The theory is it seals in any loose sand and metal and prevents dirt from accumulating in the metal pores, it also creates a smooth surface for the oil to flow over.

Probably adding a windage tray but I may just remake the pan in aluminum and build it in then. The saddle is pretty close to the crank and acts as a pseudo crank scraper. Btw, the saddle is from an 01+ 4.0, they lightened the block and added saddles to stiffen it up. It should fit all 6cyl engines in the 199/232/242/258/262(VAM) family

I have one from something that fits the 4.0 block (think it was a Ford?), It's in a crate with the other engine parts. For break in I'll be using just a regular filter, ZDDP, and some dino oil. After the break in period is done I'll be adding the oil cooler, remote filter and all that jazz

From experience, use the wide band sensor if you can work it in there. Fuel mapping is so much more critical under boost, and you just can't do it accurately with a narrow band. A narrow band sensor essentially only tells you if you're rich or lean in relation to stochimetric, but it gives you nothing other than that. You could be slightly lean, you could be running almost pure air, readings would be the same. With a wide band, you'll get much more info about your actual AFR back from the sensor.
Pricier, but worth it.

The block and head are Renix era.


Progress!

Modified subframe

Lookin good, are you going to have to run a panhard bar with that? I see the lower being triangulated but not the Upper? or is that just the picture throwing an illusion.
